Pennsylvania-born playwright and composer Quiara Alegría Hudes made her first big splash in the theater world as librettist of the musical slice of life In the Heights. Hudes’ flair for interweaving narratives took a turn for the dramatic with her “Elliot Trilogy,” a cycle of plays surrounding an ex-Marine’s search for meaning following a tour of Iraq. Skipping straight to Hudes’ Pulitzer-winning second chapter, Water by the Spoonful, the Playhouse delves into a tangled web strung together by a fractured family and an online chat room for addicts.
